Just got this. Checked compression, all good. Fired up on my stand, purring like a kitten. Go to turn the key off, and nothing. Pulled the lanyard - nothing.

This is my first Evinrude. What am I missing? Thanks

yellow black from the key must reach the EMM check for presence of ground to the switch then check for continuity from switch to engine... laynyard just duplicates the key's job (joining 2 Ms to kill) so look from key to EMM

suggest you visit theETEC owner's site dowload your manual if don'T have one

keep us posted ....feedback helps everyone !
testing for ground is the easy part

could be just a dirty contact in the #18 in diagram... or reseating the connector on the EMM work carefully on the EMM $$$$$

as an additionnal comment if new to ETECs you should consider acquiring EV DIAGNOSTIC software run on a W10 laptop ( a refurbished not expensive model with USB ports) .

EV diag is a must if you plan to pick your EMM ecu brain for any future problems .Ev diag allows tou to see all problem codes.

critical to ETECs is clean fuel, clean filters incuding a not very well known return filer in the VST ( sometimes not shown in the books)
Crumbling hoses since 2007 may... plug it up so if you do find lots of hose crumps.... feel the hoses for mushyness. if need be replace. Injectors and HPP also have base filters but...one thing at a time !!

Hose crumps can make it TO the injectors filters or simply BACK to the VST base filter.

VST hose barbs are very brittle and checking/replacing the inexpensive filter can be done bt don't break off the hose barb $$$$$$ pull it out using a large wood screw. Use proper Otieker clamps when closing up. This is a high pressure return hose from injectors.

don't forget key posts must have 0 ohm (short) M to M when OFF !! if grounds and wiring is ok
same goes for laynyard switch... to kill it must short out M wires

unlikely both functions would be bad but....murphy lurks.

Great news. Swapping harness seems expensive if just a wire was broken but if it works. Great
thanks for feedback

Might be a brp issue really. My 115 E-tec harness wouldn't turn over one winter after shutting it down for the season. Months later, I tried to start it and no starter spin or power...gauges or anything.

Screwed around a little while the key was in the on position and all of a sudden the pumps turned on loading the injectors...I was holding the harness near where it came out of the boat back by the motor well.

Long story short, took a fabric ripper and carefully snip back the outer sheathing exposing the loom of individual wires. Chased every wire with my thumb nail until I found the culprit ...hot lead.

I had extra wire so I pulled it into the outboard and redid every connection. This happened twice in 3 years.

2nd repair, I spliced in larger marine wire right where the harness exited the boat feeding into the convoluted tubing.

Turns out all the "kid tubing fun" had damaged the wire. Note, wires are ridiculously small and not marine wire (no tinning).

Never had the problem again but always wondered had I not got lucky while adjusting the harness how long it would have took to diagnose the issue. Everything was brand new (outboard, control box, harness, everything).

Not one of brp best designs if you ask me.

Hopefully this will help others.
